The RFSoC 2x2 has been discontinued. The RFSoC 4x2 is the recommended replacement.
The RFSoC 2x2 was developed by the PYNQ team in partnership with HTG. The board is based on the Zynq Ultrascale+ RFSoC Gen 1 XCZU28DR and is intended for academic teaching and research.
The RFSoC 2x2 has a Zynq Ultrascale+ XCZU28DR-FFVG1517AAZ with an Quad-core ARM Cortex A53 Processing System (PS) and Xilinx Ultrascale+ Programmable Logic (PL). The XCZU28DR has 8x RF ADC 8x DACs. The RFsoC 2x2 board has 2x RF ADCs (4.096 GSPS) and 2x RF DACs (6.554 GSPS) available via SMA connectors.
There are BALUNs between the SMA connectors and the Zynq RFSoC on the board, which means that antenna and external signal sources can be connected directly to the board.
Follow the RFSoC 2x2 getting started guide to set up and start using your board.
